Application filed February 10, 1920. Serial No. 357,668.

T 0 all whom/ may concern Be it known that I,l FRANCISGO A. QUIRoa, a citizen ofthe Republic of Mexico, and residento'f the Federal District o'f the city of Mexico, Republic of `Mexico,'have vinvented certain new and useful Improvements 1n Oil-Burners, of which the following 1s a specification.

This invention relates to improvements 1n oil burners and more particularly to the type wherein crude oil is used as the fuel. Heretofore it has been the practice when utilizing such heavy oils for this purpose, -to atomize the oilby utilizing a blast of air. Suchstructures require a large amount of mechanism for lpreparing *the oil for fuel and asoneof the principal objects of the present invention, I propose to change the modeof vaporizing the. oil in order to avoid the use ofv any complicated mechanisms such as thoseabove referred to.

Another objectof'the invention is to provide acrude oil kburner wherein the oil is vaporized by the plunging of heatedele ments therein which when withdrawn create a mixture of air with the vaporized oil which is readily'combustible and can easily n be ignited.

Another important object Vof the invention is to 1arovide a burner having a relatively few parts so that the same may be easily constructed and accessible should it be necessary to make repairs on the same.

With these and otherobjects in view this invention consists in the novel construction, combination and arrangement of parts which will be fully setforth in the following specification, claimed and illustrated in theaccompanying drawings in which Figure 1 is a side view of an oil burner and fuel tank constructed in accordance with this invention.

Fig. 2 is a top plan view of the oil burner of Fig. 1.

Fig. 3 is a transverse sectional view through the device.

Fig. 4 is a side view of the modified form of the invention.

Fig. 5 is a plan view of Fig. 4, and

Fig. 6 is a transverse sectional view through Fig. 5.

Referring to the drawings 1n detail the numeral 10 designates a suitable reservoir for containing a fuel which is led to a valved pipe 11 to the burner designated generically by the numeral 12.

The burner12 above referred to consists of a main trough 13 having its bottom curved downwardly toform a longitudinally extending pocket 14. This trough is closed by end walls 15 having recesses 16 therein for the reception of the ends of a shaft 17 upon which the burner disks are mounted.

Formed on the rear walls 18 of the trough 13 intermediate its ends, is a chamber 19 which is provided with an inlet opening 20 through which the feed pipe 11 is connected. An outlet passage or opening 21 is formed' in the wall 18 and establishes communication between the chamber 19 and the trough 13 so that the oil admitted to the chamber may enter the trough and fall by gravity into the longitudinaldepression or recess 14.

A spreader 22 is secured to the rear wall 18 and extends downwardly from a point slightly above the opening 21 to a point in a plane with the rear edge of the recess 14. The ends of the spreader iare outwardly as illustrated in Fig. 2, and the extreme forward edge 23 of said spreader is spaced slightly above the bottom wall 24 of the trough 13. It will thus be seen that the oil flowing into the chamber 19 and out through the passage 21 will be spread outwardly so that only a thin iilm is admitted to the recess 14 thereby preventing flooding the burner or in any way concentrating too great a quantity of oil at any one point.`

Mounted at spaced intervals on the shaft 17 are disks 25 which are held in spaced relation by suitable spacers 26. These disks while through experiment have operated successfully with perfectly smooth surfaces, may should it be found desirable, be perforated or otherwise roughened as at 27 to cause the oil to adhere thereto during the operation of the device. In order to rotate the disks there is provided a suitable operating mechanism such as is illustrated at 28 in Fig. 2, and it will be obvious that upon setting the device in motion the entire periphery of each disk will be brought into Contact with the oil in the trough.

As the disk is rotated it will be obvious that the oil will adhere in a thin film to each disk and upon mixing with the atmosphere will create a combustible mixture which may be readily ignited. As combustion takes place and the burner becomes heated, it will be obvious that the disks will become extremely hot 'and when their heated edges contact with the oil obviously the oil immethe vcenter of the shaft 17. It will therefore be seen that any excessive accumulation of oil upon the disks will be wiped from their surfaces before the same pass around into` position where the oil bursts into flame. And the excess Oil will be confined within the trough and thereby prevent it from interfering in any way with the proper operation of the device.

In the construction of the device illustrated in Fig. 4 to Fig. 6 inclusive, a troughis designated by the numeral 33 and the end walls 34- thereof are provided with recesses 35 in which the shafts 36 are journaled.

' Each of these shafts is provided with a gear 37 which gears are 'in mesh as illustrated in Figs. 4 and 5 and it will therefore be obvious that upon turning one of the shafts 36 the other will rotate in the opposite direction. In order to drive the device when thus constructed, a suitable operating means such as a 'motor 38 may be provided and connected Vwith one of the shafts in any preferred manner.

Mounted on each shaft is a plurality of spaced disks 39 which are held in spaced relation by suitable spacers 40 and as illustrated in the drawings, these disks intermesh. It will thus be seen that a concentrated flame from the burner when constructed in this manner is obtained without materially complicating the structure. When the burner is constructed in this manner there are provided the wipers 41 which prevents theaccumulation of excess oil upon the disks. The remaining structure is practically as that previously described, except in that the trough or pocket referred to by the character 14 in Fig. 37 is widened slightly in vorder to accommodate both disks.

While in the foregoing there has been shown and described the preferred embodiment' of this invention it is to be understood that certain minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is 1. An oil burner comprising a trough for containing fuel oil, disks rotatably mounted upon thevtrough, portions of their peripheries immersed in the fuel oil and means for rotating the disks;

2. An oil burner comprising a trough for containing fuel oil, rotatably mounted disks associated with the trough whereby their peripheries are immersed in the fuel oil and means to rotate the disks. Y

3. An oil burner comprising a trough for containing fuel oil, rotatably mounted disks associated with the trough having their peripheries immersed in the fuel oil, means to prevent flooding of the trough and means to rotate the disks. i

4. An oil burner comprising a trough for containing fuel oil, rotatably mounted disks associated with the trough having their peripheries immersed in thel fuel oilJ means for rotating the disks and wipers for preventing the accumulation of an excessive amount of oil on the disks.

/ 5. An oil burner comprising a trough for containing fuel oil, a pluralit. of rotatable.

disks associated with the troug said trough having a chamber communicating therewith for conducting the fuel oil there into, a spreader within the trough for preventing the iiooding of the trough with fuel oil and wipers between the disks to avoid theV accumulation of an excessive amount of fuel oil on the disks, and means to rotatey said disks. c
